IMPROVEMENT IN QAS-RETORTS AND HEATlNG-FURNACES.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern: I

Be it known that I, GOLDSBURY H. POND,"of Rutland, Rutl'and county, in the State of Vermont, have invented an improved Gas-Retort and Heating-Furmice; and I hereby declare the following't-o be a full and supply steam, melted grease, oil,&c., to the tire while it is hot, so as to make the gaswiththe fire within the retort Also in arranging the water or steam-heating pipe between the soap-stone orfire-brick liningand the outer case of the furnace, and ma device for opening and closing the smoke-fine when it is used as a retort and without the stove or range.

In the accompanying drawing- Figure 1 shows a retort constructed to make gas and serve as a heatingfurnace.

Figure 2 shows a retort in combination with a cooking-stove or range.

-I prefer "to make my retorts of iron boiler-plate, with a cylinder, A, bottom, 13, and top, 0, all firmly fastened together inside the cylinder A.

I arrange a tilting-grate, 'I), for the fire, and an.

opening, E, in the side tor draught, rakingthe grate, and removing the ashes.

Also an opening, F, in the top to supply'fuel, which is closed by the plate G and secured by the bar H, as shown in fig. l. v

I is an opening for the escape of the smoke, provided with a door, J, shown in fig. 3, for closing it; and when this door is open, as shown in dotted lines, the smoke passes up through the opening K.

On the inside of the cylinder A, I coil the waterpipe L for making steam and heating water, the water entering at M and escaping at N; and, inside of the pipe L, I arrange the soap-stone or iire-brick lining, so that the water-pipe is between the lining andthe cylindex. I

"The pipe P is for supplying the melted grease, oil, &;c.,tbr making gas, which pipe may be provided with Some proper means for distributing the oil or grease over-the tire. I

Q is the pipe for supplying steam under the grate,

forth.

from some boiler,to aid in making the gas; or the steam may be taken from the coiled pipe L.

. 1n fig. 2 the retort is shown with a cooking-stove or range above it.

When I make the retort-to be used with a stove, I make a trough, It, around the. opening F in the top, and supply itwit-h lead or some metal that will melt at alow temperature, and make a cover, S, to project down into the melted metal and make a gas-tight joint as shown in section, fig. 4. v

1 make the bottom-plate of the ovcusT 'l to extend across between the ovens; and make an o n-ning, U, in the plate, right over the opening 1*,to-supply fuel-to the retort through the boiler-hole V in the top of the stove. After the fuel is'put in, the opening U is closed by the cover W to make the smoke pass around the ovens and out-into the pipe X applied to the hack of the stove between the ovens.

To use the retort, a fire is madevin it, which may be used to heat the stove and do the cooking, and also heat a house or hotel; and when the cooking is done for theday, and while the fire is hot, the cover J must be luted with clay and made tight, also the draughtopening E and the cover S put on, when the mc'lted grease or oil must he run into the retort through the pipe Rand a supply of steam through the pipe Q, when the-tire will make the gas, which will pass out through the pipe Y into a gasometer, fron1 which it may be used as it iswanted.

What I claim as my invention and improvements in gas-retorts and furnaces is- 1. A gasretortso constructed and arranged as that a fire may hemade within it' as a furnace for heating buildings, boiling, and cooking, and, while-thefire is incandescent or.\'cry hot, close the draught-opening and smoke-escape, and supply steam, melted grease, 85s., to the fire while it is hot, so as to make the gas with the fire made within the retort.

.2. Arranging the steam or water-heating pipe in furnaces between the soap-stone or fire-brick lining and the outer case of the furnace, substantially as de- GOLDSBURY H. Pom).
